With the wide lot use of computer systems comes the threat of hornswoggle programs that damage the system and other programs on that system. T hese short programs are called computer viruses. There are many computer viruses out there to infect unsuspecting system and programs. Along with these threats of infection comes the opportunity to take away these viruses before they infect systems. There are programs called anti-virus protection to help find and fix problems before they damage computer systems (Encyclopedia.com).Computer Virus and ComponentsA computer virus can be defined as a rogue computer program, usually short in nature, designed to spread copies of itself to other computers and chop off the computers normal operation. These viruses usually attach or insert themselves in or to a program or boot sector of a disk. It is spread through and through floppy disk, network, or routine on-line services. There are some viruses that are harmless, but others can destroy or corrupt data and amaze an operating system or application program to malfunction. The three most common types of destructive computer programs are th e Trojan horse, logic bombs, and the worm. A virus is considered to be a worm with a logic bomb or Trojan horse component (PC Upgrade).Worms are programs that copy themselves. They create images of themselves in a file or a certain part of a disk. The main reason for including a worm component in a virus is to spread the virus via floppy dick. Now everytime you format a disk or copy a disc, the worm now infects you floppy disk. The Trojan horse is a program hidden inside another useful looking program. When the useful program is running the Trojan horse is doing something like erasing your Fat and directory. The last of this triangle is the bomb. The bomb is a piece of code embedded in a program or the operating system that waits for a particular event to occur.
